traveling back in time is not mathematically disallowed by the general relativity.
in fact there is a lot of work done on the topic, and lots of potential scenarios proposed (which usually involve describing the space-time warped into weird 4D shapes). what GR does tell you is what kind of matter/energy would produce such spaces (since in GR these two are intertwined), and that’s kind of where common sense works again: most proposed geometries do require either negative energy densities or mathematical singularities (which to be fair are not impossible, but we kinda never seen that, aside from dark energy).
on the other hand – faster-than-light travel is also possible – albeit with similar constraints.
traveling back in time is not mathematically disallowed by the general relativity.
Moving mass backwards through time isn’t strictly mathematically disallowed. Idk what it’s going to look like when it arrives, though.
What does a Tachyon even look like?
i didn’t mean purely mathematically. but from the physics standpoint. in other words, if you provide enough dark energy and shape it into a specific configuration, it will generate space-time where time travel is possible in practice.
The Appalachian Mountains are older than trees.
Sharks are older than The North Star
Like the sharks swimming right now
Well… some
speciesdivisions live for hundreds of years. So there may be some swimming around older than when some younger countries were founded.
Every single one of us is travelling through space on a tiny speck of dirt, circling a permanent explosion that doesn’t know how to stop itself at 30km/s.
That explosion and multiple specks of dirt besides our own dance around the center of the galaxy in a complex ballet with 200 billion other permanently exploding balls of fire and plasma, many of which are sizeably larger than ours and also have collected pieces of dirt circling around them, at a speed of 200km/s. The center of this agglomeration of giant balls of fire and dirt is a… thing… that is in itself so massive it can’t help eating everything that comes near including suns, light, and the concept of time.And there, travelling around the center of the galaxy at 200km/s, spiraling around your sun at 30km/s, there is you. And somehow you have to work tomorrow.
So full of it. I don’t work on Saturday.
I was thinking about putting a reference to that in, but decided it would be a bit trite.
The average human being has (approximately) one testicle and one ovary.
The average human has more than one brain
Hmmm. I don’t beleive this one. I know a lot more brainless people than I know multi-brain people.
and less than two arms!
Oh you fucke-
Males can lactate apparently.
Still can’t sleep at night.
Am man. Can confirm.
deleted by creator
Anyone can lactate with a course of lactation inducing medication (of which there are several iirc)
Or with about 30 days of stimulation training, which basically involves using a pump on your nipples multiple times a day.
Males have all the mammary glands plumbing already built in?
Yes.
Men are fully equipped to lactate. They just typically lack the hormones or stimulation to trigger it naturally.
They do, they have breast tissue, even if very little. Which also means that men can get breast cancer.
But women have milk ducts, an essential body part to develop & channel milk. Do men have milk ducts?
Milk ducts are just a specialized sweat glands, it’s not the same but it works.
I thought it was a disorder.
…
So you are telling me I can legit be a hu-cow and have…
…people eat/drink a part of me? 🤩
You can have you-milk on your cereal in the morning.
I have nipple, can you milk me?
Of course hon! 12$/h
Bloodletting is still a legitimate medical treatment, now called therapeutic phlebotomy.
Some medicines, like testosterone, can increase your hemoglobin or blood count, so giving blood is the fix for it.
Testosterone, even when taken at supraphysiologic dosages, rarely causes erythrocytosis to an extent that therapeutic phlebotomy is necessary.
Other anabolic steroids, particularly Equipoise (aka Boldenone), increase red blood cell count significantly more than testosterone.
Hemochromatosis, too. Body doesn’t eliminate iron so it can build up in organs, notably liver and kidneys.
The treatment is bloodletting. My wife wanted to get leeches. I settled for just donating 32 times in the first year after finding out. My ferritin count was 9 times the usual max for a man my age. My gallbladder fluid was carrying iron. I was Iron Man.
A leech tank would be pretty metal though. Like, imagine the medieval lord aura of leeching at a dinner party.
You’re a hero, Iron Man!
There are more grains of sand on the planet Earth than there are stars in the solar system.
Our solar system? So, more than 1?
Yeah. It’s like saying what weights more, a KG of iron or a KG or feathers.
That’s right, it’s a kilogramme of steel, because steel is heavier than feathers!
At standard temperature and pressure, the iron. You gave a unit of mass but asked which weighs more. The feathers are more buoyant. Both negatively buoyant in air of course, but the feathers less so.
Kg of iron. Iron is heavier than feathers
No, you see, they’re both a kilogram, Limmy.
Ethanol can help protect your liver from the damage an acetaminophen overdose causes.
You’d think that doubling up on liver harming substances would have an additive effect, but nope.
Similarly, ethanol can help protect you from the poisonous effects of methanol (wood alcohol). Methanol by itself isn’t actually harmful, but it gets broken down into harmful byproducts that will make you go blind and then kill you.
The enzyme responsible for breaking down methanol is also used to break down ethanol. And enzymes have a limited capacity for work. In other words, they can only break down a certain number of molecules at any given time. And the enzyme is more compatible with ethanol than methanol.
So if you suspect someone drank methanol, (it is a common ingredient in antifreeze), you should have them start taking shots. Pump them full of as much liquor as possible, as quickly as possible. Get them absolutely shitfaced ASAP, and keep them wasted until they get to the hospital. It will prevent the vast majority of the methanol from being broken down, which will prevent the actual poisoning from happening.
It’s ethylene glycol that’s commonly in antifreeze, but ethanol protects against that too. I believe methanol is common in windshield wiper fluid, though.
sounds like the modern automobile is a treasure trove of delicious treats.
Pretty much. Mazda had an issue with spiders attracted to gasoline clogging up fuel systems while being shipped overseas. And soy-based wire sheathing is apparently quite the delicacy to certain animals.
Why do you think so many fluids are juice colors?
I think all my problems could be solved with a nice big glass of Window fluid or Antifreeze.
Rabbits must eat special poop straight from their butt as a part of a healthy diet.
What about other rabbits’ poop?
I haven’t seen it happen, but I wouldn’t be surprised.
My girl bun does stick her nose up my boy bun’s butt sometimes. But I think that’s just to nip his thighs and get him to move out of her way lol
Oh! I forgot, mama rabbits feed their special poops to their babies. So the answer is, yes, they do eat other rabbit’s poops.
Everything about fecal transplant. Or maybe just the fact that it is even a legitimate medical procedure
Not fun fact: That’s how I became lactose intolerant

“Wow, Mr. Blake! The results of your medical trial were astounding! These are excellent results!”
“Wait…huh?”That really is a shitshow, indeed.
There are over 100 volcanos on Antarctica
Active or dorment?
I like this fact and as a geologist I’m a little numb to facts about the Earth. At some level, all land on Earth has a volcanic origin by virtue of us having a molten core, a rigid mantle, and a crusty crust that seeps magma/lava. Time metamorphoses and sediments the rock in different ways. Antarctica just had the misfortune of migrating to the South Pole where millions of years of snow fall lead to its icy encapsulation.
The good news is it’s all melting! Antarctica can be free!
If you get methanol poisoning for example from badly made liquor then the remedy for that is to drink ethanol (good liquor).
I always keep a bottle of medicinal vodka around.
Also glycol poisoning. Like if you drink antifreeze for your car, one treatment is to drink a bunch of alcohol so the liver processes the alcohol and not the ethelyne glycol.
thanks for the tip, now im less likely to be poisoned by an assassin.
Is this for real? Any links? Not doubting you but it’s always been a dark thought I can’t push away about accidentally drinking that stuff.
This one talks about injecting ethanol straight into the veins for quick absorption. https://scienceinsights.org/treating-ethylene-glycol-poisoning-antidotes-and-dialysis/
Or this one. Skip to “ethanol treatment” https://archive.cdc.gov/www_atsdr_cdc_gov/csem/ethylene-propylene-glycol/treatment.html
I saw on TV where a woman tried to poison her husband with antifreeze, but since it was mixed with alcohol it took him more than a week to die.
Same with acetaminophen poisoning.
France is bigger at Christmas than at Easter.
Reason: Pheasant Island.
Frances longest border is with brazil
The volume a liquid takes up varies DRASTICALLY based on temperature and pressure.
Bonus fact. A significant amount of sea level rise due to climate change is caused by thermal expansion of the water.
Hot liquids can freeze faster than colder ones Mpemba effect
Many studies of this are actually ambiguous!.
deleted by creator
But ambiguity arraises from the lack of a coherent explanation, because there are so many parameters to consider when doing the experiment (especially when doing this with water). Therefore hot liquids can freeze faster than cold ones. Its not a must. That it can happen is proven. A quite entertaining read about the general phenomenon can be found here
No, it doesn’t. The ambiguity rises from the fact that it’s not that repeatable. There are many experiments that don’t find this phenomenon to exist when they test it. Then there’s some that do. That’s the problem.
My memory is that the majority of them find that it doesn’t exist and that a small minority find that it does.
This is not contradicting. It can happen . but I was talking about liquids in general.
Looking this up, I just realized that Francis Bacon and Roger Bacon were different people.
Knowledge is power. France is bacon.
Don’t leave poor Kevin out
Meanwhile you’re completely ignoring Michael.
Who the fuck is Micheal Bacon?!
Are you rinding me up??
Literally the other half of The Bacon Brothers!? That’s who you meant, right? Kevin Bacon, the singer? Well, he didn’t become famous alone.
First time I’ve heard of Hermanos Beicon
I bet that family got taste!
